accessibilityValue property

@override String get accessibilityValue

A value summarizing the chart's data — counts, range, a few points.

Implementation

@override
String get accessibilityValue => slices.isEmpty
    ? 'No data'
    : '${slices.length} slices, '
          '${AccessibilityFormat.points([for (final s in slices) (s.label, s.value)])}';
